The Fit4Launch Call & Voice Measurement System, Nomad, is a uniquely scalable, centralized platform utilized by leading carriers and OEMs to evaluate and improve voice quality and call performance in 2G, 3G and 4G devices. Nomad leverages patented voice quality testing technology, which enables you to test thousands of calls automatically to or from the device and instantly generate performance statistics, saving precious time and money when launching a new device. Nomad enables large-scale performance testing for new device launches, post-launch troubleshooting and competitive benchmarking. As 3G and 4G networks increasingly drive converged voice and data traffic, Nomad enables service providers to assure call and voice quality in a multi-radio bearer (multi-RAB) scenario. Nomad is considered the most comprehensive, accurate and easy to use mobile call and voice user experience measurement platform commercially available.
Advantages of Nomad:
Nomad was developed to assist the world's leading mobile service providers and OEMs with a robust and reliable way to evaluate mobile device performance for the most repeated task: voice calling. The local client connects to multiple handsets, regardless of operating system or access technology, via Bluetooth or electrical coupling, enabling testing of subject and reference devices, and call performance and voice quality, simultaneously. The client connects to Metrico-hosted call and voice servers, available globally with guaranteed access and levels of service, to complete calls and automatically receive data for instantaneous analysis. This system enables rapid, rigorous and large-scale measurement and analysis of devices in the lab and the field.
Nomad addresses common challenges for mobile service providers and device OEMs:The Nomad Call Performance & Voice Quality Measurement System comprises:
By exchanging thousands of samples of uplink and downlink recorded speech or DTMF tones, and employing the echo-back test to further verify correct operation, the system provides a fair and representative analysis of the device's performance. The client can be configured to automatically synchronize data from the servers, to enable instantaneous and sophisticated analysis at the local level.
Nomad does not require any additional hardware (non-tethered) so the tests closely mimic your subscribers' experience.
Nomad is mobile device neutral. This means the tool can be used for any mobile operating system and mobile device you want to test, significantly reducing the hassle, time and costs associated with testing and launching different devices over time.
As part of Metrico's global infrastructure, Nomad has call and voice servers launched worldwide to allow for accurate performance testing no matter the time zone. Additional infrastructure can be deployed to meet client requirements.
